Pyrotechnics Keep Getting Greener
Fireworks are beautiful, but their color-burning components—often perchlorate-based mixtures—are less than environmentally friendly. Scientists, including Jesse J. Sabatini of the Army’s Picatinny Arsenal, in New Jersey, have been working to develop less polluting compounds for pyrotechnics used by the military and for public display. For example, scientists recently synthesized high-nitrogen nitriminotetrazolate salts, which served as perchlorate replacements in pyrotechnic mixtures. But the high-nitrogen salts were not commercially available. In addition, producing a . . .
